Why does the light steel keel machine have paint scratches on the bottom wheel?

There are mainly three reasons for the problem of the bottom wheel scratching the paint on the light - steel keel machine:

This reason is mainly related to the  (pre - commissioning). Generally, for newly purchased equipment, the light - steel keel machine manufacturer will send technicians to assist with the operation and conduct commissioning. If the problem lies in incorrect commissioning, you can directly contact the light - steel keel machine manufacturer to make adjustments and conduct retesting until the problem is resolved.

There is another possible cause of paint scratching. After some light - steel keel machines have been operating for a long time, their bottom wheels may become loose and shake back and forth. This is the result of an increase in deviation. If this is the cause, the problem can be solved by reducing the deviation.

The third cause of the bottom wheel scratching the paint is the problem of the bottom wheel itself. On the one hand, it may be affected by some extra objects stuck. Imagine that there are some irrelevant sundries shaking beside the high - speed rotating bottom wheel. How could there be no problem? On the other hand, it is due to the fact that the distance between the wheels is too narrow, resulting in excessive friction. If this is the problem, how to solve the problem of the bottom wheel scratching the paint on the light - steel keel machine? It's very simple. Just increase the gap between the upper roller and the lower roller. Generally speaking, when the gap is increased, the friction will be reduced, and the problem of paint scratching will be easily solved.
